for the last 8 months i havent been able to be myself

To who it may concern.. My name is Michelle and I am 18.
Since 8 months ago, I have felty severly sick, and been in & out of Hospitals.

It hits me randomly, and when it hits.. it hits hard.
I could be out with friends, or sitting with my family.. and it happens>
All of a sudden I feel SWEATY, my head drips and hands go cold or SWEAT dripping, my head sometimes hurts, and if it doesnt hurt its a buzz/blur in my ears and i cant hear right..followed by a pain in my left side.... then i feel like im going to be sick, have direhha, or puke..... i always lay down for a while and it goes away.. but this has been happening so much.** I KNOW MY BODY and something isnt right.. This has been effecting me very negatively.. as for at work and school.. I currently dont work because i am scared I am going to pass out..

I have been to hospitals, and my white blood cell count is HIGH***

I could be standing in a kitchen at my friends, get the symptoms* and pass out on her floor..
i dont want this to happen anymore, and im scared..

i have been to toronto doctors,orillia,barrie and midland..
I have been tested for diabetes, cancer, i have had a scope test LOWER GI. and for parasites.

The worst part is... the pain I have in my lower left side which sometimes moves towards my belly, the doctors told my mom and I that that pain was sicological and that it was all in my head..
That really has upset me, and I know my body for something is wrong!**
none of this is normal to me!

as i lay here, and type this up I hope someone can help...
because the doctors cant... they have no idea whats happening, i just want to live my teenage life and have fun... and for the last 8 months i havent been able to be myself..*
someone please help...
thanks
